Former Treasury Secretary Larry Summers made his distaste for the Trump administration’s tax framework clear last week when he said Republicans were using “made-up” claims about the plan and its effects. Summers expanded his criticism on Tuesday in a blog post that took aim at the report released Monday by the Council of Economic Advisers and chair Kevin Hassett, which seeks to justify the administration’s claim that its tax plan will result in a $4,000 pay raise for the average American family.

Never one to mince words, Summers says the CEA analysis is “some combination of dishonest, incompetent and absurd.” The pay raise figure is indefensible, since “there is no peer-reviewed support for his central claim that cutting the corporate tax rate from 35 to 20 percent would raise wages by $4000 per worker.” In the end, Summers says that “if a Ph.D student submitted the CEA analysis as a term paper in public finance, I would be hard pressed to give it a passing grade.”

One of the authors cited in the CEA paper also has some concerns. Harvard Business School professor Mihir Desai tweeted Tuesday that the CEA analysis “misinterprets” a 2007 paper he co-wrote on the dynamics of the corporate tax burden. Desai’s research has found a connection between business tax cuts and wage growth, but not as large as the CEA paper claims. “Cutting corporate taxes will help wages but exaggeration only serves to undercut the reasonableness of the core argument,” Desai wrote.

Although there may be plenty of things in the GOP tax bill to complain about, critics can’t say it didn’t work – at least as far as stock buybacks go. TrimTabs Investment Research said Monday that U.S. companies have now announced $1 trillion in share buybacks in 2018, surpassing the record of $781 billion set in 2015. "It's no coincidence," said TrimTabs' David Santschi. "A lot of the buybacks are because of the tax law. Companies have more cash to pump up the stock price."

Budget deficits normally rise during recessions and fall when the economy is growing, but that’s not the case today. Deficits are rising sharply despite robust economic growth, increasing from $666 billion in 2017 to an estimated $970 billion in 2019, with $1 trillion annual deficits expected for years after that.

As the deficit hawks at the Committee for a Responsible Federal Budget point out in a blog post Thursday, “the deficit has never been this high when the economy was this strong … And never in modern U.S. history have deficits been so high outside of a war or recession (or their aftermath).” The chart above shows just how unusual the current deficit path is when measured as a percentage of GDP.

About 4.2 million uninsured people could sign up for a bronze-level Obamacare health plan and pay nothing for it after tax credits are applied, the Kaiser Family Foundation said Tuesday. That means that 27 percent of the country’s 15.9 million uninsured people could get covered for free. The chart below breaks down the eligible population by state.

Vox’s Ezra Klein says that retiring House Speaker Paul Ryan’s legacy can be summed up in one number: $343 billion. “That’s the increase between the deficit for fiscal year 2015 and fiscal year 2018— that is, the difference between the fiscal year before Ryan became speaker of the House and the fiscal year in which he retired.”

Klein writes that Ryan’s choices while in office — especially the 2017 tax cuts and the $1.3 trillion spending bill he helped pass and the expansion of the earned income tax credit he talked up but never acted on — should be what define his legacy:

“[N]ow, as Ryan prepares to leave Congress, it is clear that his critics were correct and a credulous Washington press corps — including me — that took him at his word was wrong. In the trillions of long-term debt he racked up as speaker, in the anti-poverty proposals he promised but never passed, and in the many lies he told to sell unpopular policies, Ryan proved as much a practitioner of post-truth politics as Donald Trump. …

“Ultimately, Ryan put himself forward as a test of a simple, but important, proposition: Is fiscal responsibility something Republicans believe in or something they simply weaponize against Democrats to win back power so they can pass tax cuts and defense spending? Over the past three years, he provided a clear answer. That is his legacy, and it will haunt his successors.”
